Abstract:
We examine the linear stability of the steepened backside of two-dimensional ionospheric barium clouds. We derive expressions for the growth rate of perturbations on these backsides which are functions of 1 the ratio M of the integrated Pedersen conductivity inside the barium cloud to that of the background ionosphere 2 the overall shape of the cloud 3 the plasma density gradient scale length L of the steepened backside and 4 the perturbation wavenumber k. For sufficiently small kL, the growth time as a function of M traces out the U-shaped curve observed in previous studies. Author
